nsync is a portable C library that provides a collection of advanced synchronization primitives designed to facilitate safe and efficient multithreaded programming. It offers reader-writer locks, condition variables, run-once initialization, waitable counters, and waitable bits for coordination and cancellation between threads. Unlike traditional pthreads-based synchronization, nsync introduces conditional critical sections, allowing developers to wait for arbitrary conditions without explicit signaling or complex loop-based logic. ...

...Many popular registries like Docker Hub, GCR, and GHCR are located overseas, often causing significant delays when pulling images. This project solves the problem by offering mirrored registries with consistent image hashes and real-time synchronization. It uses a lazy-loading mechanism, caching image layers in third-party object storage, ensuring that frequently used images are delivered faster. The system is simple to use, requiring only a prefix replacement to pull images from the mirror instead of the original registry. By reducing latency and improving reliability, the service supports developers in accelerating Kubernetes, Docker, Containerd, and AI model image downloads in production environments.
